I don't really understand what you mean with: "The car is listed as "both" a 85D and a 75D."
I don't see that listed anywhere. But just to clear it up, no, there is no such thing as an 85kwh battery limited to 75kwh. They aren't at all the same type. That must be a typo or mis-labeling somewhere if you do see that. The batteries that were 60, 70, and 75kwh are all built with the 350V architecture. The 85, 90, and 100kwh are all 400V.

But if you look at the Norway inventory listings page, that same car shows up as an 85kWh car:

This is why I am asking, though, because only one of your "two" pieces of information works. Yes, I can see the screen shot that shows an 85D, but the other link you give that says 75D and a VIN doesn't work. It doesn't go to a specific car listing when I click on it. It just redirects to Buy a new Tesla today | Tesla
So yes, I see an 85D screen shot but nothing that says 75D.

Sorry, I didn't mean to imply that--just that the link wouldn't work for me, so there was no information I could see from that. I'm sure it was from Tesla's redirecting, but I couldn't figure out how to get around that.

This really looks like one of those cases where someone made a clerical error, typed something wrong, and a car ended up labeled wrong or in the wrong section of the website. It's a bit like if someone in a grocery store dropped an apple in the bin where the bananas go, and some people started seeing it and coming up with this wild idea that it's a top-secret new genetic hybrid that makes red spherical bananas now!

Well, to be fair, one would be a low level clerical error to be fixed, and the other a corporate-wide strategic change going against a deeply ingrained corporate culture..

One is a little easier to fix.

Yes, that is quite true. So let's look at small technical software bugs, like the audio unpausing bug they introduced in 7.1 (still not fixed), and the USB song ordering when browsing by folder they screwed up in 8.0 (still not fixed). I know, griping at this point. It's just the Gordian Knot thing, that this is much more likely to be multiple typo screw ups than a new 75/85 type battery. The incredibly fast growth would indicate this as well, as they have more and more to do, and people are getting more and more rushed, as they have a hard time hiring and training fast enough in some areas.

I think they just want to move those discontinued 90kWh cars and I don't see how it would help them to sell them as 75kWh. A 90D sold a lower price is far more appealing that a 75D without any discounts. To me limited supply is really just equal to "inventory clearout".

The recent New Inventory Tesla X75D's are showing the new battery code BTX7 instead of BTX5. Seems like a new battery is being installed in Tesla's that are recently manufactured. These are also showing BR05 instead of BR00.

Another product change at Tesla ramping up silently - or simply getting rid of some old battery stock?

Well... this would certainly be consistent with the the Tesla way. I could see a little option popping up on recent 75kwh cars, offering to upgrade to 85kwh for X$.

This raises a whole series of questions.

1. Is this hypothetical new 85 the result of chemistry improvements or of adding cells?
2. The 100D and 85D suddenly come very close in capability. The price gap has to close. What will give?
3. OR, the more interesting possibility, do we see a bump in the 100D battery?

I'm hoping for #3, of course! It should be an interesting week![/USER][/QUOTE]

Tesla wants to save money and share parts as much as possible across their vehicles. The 90 and 75 had the same modules, just different numbers of them. The small pack had 14 modules and the large pack 16. The 100 pack has a denser module with more cells and is actually 102 KWh. If they make a pack with 14X modules used in the 100 KWh pack, it would come out to about 89 KWh and it will actually be higher capacity than the old 90 pack which was around 86 KWH.

I think this is just Tesla consolidating production to only make 1 module again and package them with 14 or 16 modules. Just the improvement in the pack alone would explain the acceleration increase in the 75 announced on July 1.

The 75 has been limited by the power the pack can put out. The 90 was mostly limited by the motors. The 100D got a slight improvement maybe because of the new drive unit and inverter, or it might have just been the larger battery pack that could deliver more current. In any case, people don't generally decide on a 75 or 90 based on the performance, people bought the 90 for range and the 100D will continue to be the range king. I expect once they reveal the new 75 is really an 85 (really 89 and they could market it as a 90), it should have around 300 miles range. The entry level S should also have better range than the top of the line Model 3.

They may raise the price of the new 85 (or 90) when they announce it to bring it a little closer to the 100.

I've been expecting a new 85 or 90 since late last year when the 100 was introduced. When the old 90 was discontinued, I knew the end of the 75 was not far behind.
